SUS06-BP04 Use managed device farms for testing

Use managed device farms to efficiently test a new feature on a representative set of hardware.

 **Common anti-patterns:** 
+  You manually test and deploy your application on individual physical devices. 
+  You do not use app testing service to test and interact with your apps (for example, Android, iOS, and web apps) on real, physical devices. 

 **Benefits of establishing this best practice:** Using managed device farms for testing cloud-enabled applications provides a number of benefits: 
+  They include more efficient features to test application on wide range of devices. 
+  They eliminate the need for in-house infrastructure for testing. 
+  They offer diverse device types, including older and less popular hardware, which eliminates the need for unnecessary device upgrades. 

 **Level of risk exposed if this best practice is not established:** Low 

## Implementation guidance
Implementation guidance

Using Managed device farms can help you to streamline the testing process for new features on a representative set of hardware. Managed device farms offer diverse device types including older, less popular hardware, and avoid customer sustainability impact from unnecessary device upgrades.

 **Implementation steps** 
+  Define your testing requirements and plan (like test type, operating systems, and test schedule). 
  +  You can use [Amazon CloudWatch RUM](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-RUM.html) to collect and analyze client-side data and shape your testing plan. 
+  Select the managed device farm that can support your testing requirements. For example, you can use [AWS Device Farm](https://docs.aws.amazon.com/devicefarm/latest/developerguide/welcome.html) to test and understand the impact of your changes on a representative set of hardware. 
+  Use continuous integration/continuous deployment (CI/CD) to schedule and run your tests.

+  Continually review your testing results and make necessary improvements.
